REFUSE-INCINERATOR CONSTRUCTON AND SHOPPER DOR THREFOR i Applicationfiled April 13,

This invention relates to refuse disposal construction in the nature ofthose associated with incinerators and more particularly to hopper doorstherefor. Y

Where I have attempted to provide in building construction refusedisposal chutes or flues whereby ashes, garbage or similar refuse may bedeposited and gravitated to receiving receptacles or consumedin anincinerator, considerable difficulty has been encountered by reason ofthe draft created attendant to opening and closing of the flue openingstending to Whirl particles of dust or still more objectionably drawingin odors of burning refuse.' Where the flues are used in connection withheating plants, the element of loading of these flues for depositingrefuse therein has been a still further objectionable source ofdisturbance to the bed of fire, creating drafts serving touneconomically consume the fuel. Aside from these ditculties, wherethese disposal devices are used in households, a tendency to overloadand jam the flue opening with refuse has been occasioned by thecontinuous opening permitted by doors used in connection withincinerator constructions lmown to me, still further adding to thedifficulties encountered as above enumerated, during use, as the periodof loading is thereby further increased.

My invention therefore has for an object thereof the provision of arefuse disposal construction such as incinerators and hopper or closurelmembers for the flue thereof, permitting loading without disturbing thecurrents of air in the flue opening, characterized by a door or hopperwhich serves toseal the fiue opening under all conditions of use; theprovision of a refuse disposal flue 4having a loading door or hopperforthe loading opening thereof characterized by the door or hopper servingas a seal for the loading opening in any position thereof; the provisionof a refuse disposal system or incinerator, and a loading door orhopperv for the loading opening thereof comprising a pivotallypartitioned member coacting with the arcuate guiding walls in theopening, with the partition members serving to seal the opening in allpositions; the provision of a hopper 1927.

door for the feeding opening of an incinerator flue comprising a pluralpartitioned, pivotally mounted member' associated with an ar-' cuatewall in the opening of said incinerator whereby one of said partitionson said member may be in contact with the arcuate wall to Y seal theopening under all conditions of use,

thereby avoiding the induction of dust or noxious gases into the livingroom and avoiding any disturbance in the fuel bed by setting up drafts,normally occasioned by the loading and opening of the hopper door.

My invention still further has Vfor anob-v l ject thereof the provisionof a hopper door` for a refuse disposal systemjsuch as incinerators,characterized by simplicity of construction, economy of assembly,pleasing inappearance, and at-the same time including fea-V tures suchas leaving substantially undisturbed the air pressure inthe flues ofanincinerator by avoiding the creation of-drafts and the induction ofobjectionable dust andgases into the living room when loading or.otherwise using the incinerator system. Still" further, my inventioncontemplates the provision of a hopper door for incinerators which willnot become out of order, occasioned by over-stuffing of theflue opening,characterized by they provision of a hopper door which 'at' no timepermits direct feeding-of refusematerial to the flue. i 1 l To attainthese objects and such' further objects as may appear herein or behereinafter sol pointed out, I make reference to the accomf4V panyingdrawing forming'aV partV hereof, Yin whichv v j Figure 1 is a sideelevation in section show-.1 ing 'my device as connected to the-wallofan incinerator flue; Y n w Figure 2 is a view similar to Athat Ashown inFigure 1 in the closed position;

Figure 3 is a front elevation. H Making reference to the drawings, itwill be observed that my device maybe applied to the wall 10, having anopening generally referred to 11, connectingv with the flue or shaft andextending laterally into the interior of the room fromwhichV refusematter, garbage, ashes or the like may be deposited to the flue, leadinginto a storage device, incinerator or the like. The constructionpermitting loading into the opening comprises a y frame referred togenerally at 12, preferably tially 90.

made of a frontal section 13 and a rear section 14, having inwardlydirected flanges 15 and 16 overlapping, through which may be passed arivet or similar fastening device 17.

The frame is further provided exteriorly thereof with a plaster bead 18adapted to lie flush with the inner face of the wall 10. The

frame 12 is provided with a main vopening defined by the inwardlydirected` side wall flanges 19, the upper wall 20 being formed arcuatelyas a segment of a circle of substan- This arcuately formed portion maybeincluded entirely by the section 13.

rPreferably, however, thisl arcuately formed wall is disposed to have aportion thereof 21 formed in the frontal portion 13 and an additionalportion 22 formed in the rear portion 14 so as vto be contiguoustherewith. Upwardly extending flanges 23 and 24 form lap joints throughwhich may be passed a fastening member such as a rivet 25. The

l bottom wall of the opening is preferably vformed withdownwardlyjinclinedwalls 26 i formed in the frontal portion 13 and inalign tion members 31 and 32, disposed substanment with the portion 27formed in the rear frame 14.- The side walls 19, 19 of the frame areprovided adjacent the bottom wall 26 with offset bearing portions 28,28. These bearing portions are preferably downwardly inclined slotsforming bearing seats 29.

Into the openingV just described, there is` disposed a hopper door30,'including partitially at right angles to each other, and side wallsv33 arcuately shaped, corresponding to the arcuately shaped wallsi21, 22above described. A handle member 34 is provided on the partition wall 31for suitably operating the hopper in a manner which will be apparent as?this description proceeds. The side walls 33 are provided with bearingpins'35 f which Yare positioned adjacent the corner formed by theintersection of the partitions 31 and 32. The curved Walls 33 arepreferably set ofi Valong the edge 36 between the edges A37 Vand 38 ofthe partitions numbered 31 and 32,-respectively. Y y

To position the hopper 30, this member is inserted in the opening, firstinsertingthe edge 38, until the pins rest in the bearing Vportions 28,upon the seat 29. The hopper 'lower edge 40 of the wall 22; In this ber31, further serving to seal the opening 11 and acting as a stop incooperating with the bottom wall to prevent furtherV rotation. This lug39 is positioned about midway of the arcuate wall formed by the portions21 and 22 and extends across the full length thereof. For loadingmaterial into the incinerator flue, rotation is given to the hopper doorby grasping the handle 34. In Yits rotation inwardly about the pins 35,it will be observed that the partition member 31l serves to seal theopening throughout its movement until the position substantially shownin dotted lines in Figure 2 is reached. As the partitions 31 and 32 arepositioned to subtend an angle equivalent to that of the arcuate walls21 and 22 in the position shown in dotted lines inv Figure 2, the edge38 will Vbe adjacentthe tion, it will be observed that the innerpartition member 31l is just passed'theI opening defined by the sidewalls 1,9 and 20. Here, again, in this position it will bezobserved thatthe partition member 32 serves to seal theV Further movement opening 11of the fiue. Y inwardly to that shown in Figure 1 maintains the edge 38in substantial contact with the arcuate wall 22 until the edge 38 abutsthe lug 39, preventing further rotation. In'this position, however, thepartition member 31 has passed the edges of the walls 19 and 20,

giving access to the interior of the hopper.'

In this position, refuse material may be load"- ed into the hopper doorto completelyl fijll ther same. It will be further observed thatv nomaterial may be forced into the flue opening posi- 11 beyond thecapacityof the hopperV 30.

Furthermore, in its loading position, thepar` tition memberY 32serves'to completely close and seal the opening 11. y

To unload the contents deposited within the hopper 3Q, pivotal rotationto the right isv effected until the partition member 32 rests upon theangularly -disposed walls. 26

and 27 and the edge 37 of the wall 31 abuts the lug 39. The materialdeposited within the hopper will thereupon `gravitate down the inclinedangularlypositioned wall 32 into the'flue directed to any receptacle 0rincinerator. I Y

It will be observed that the partsma'y bel made of suitable fireresistant material such as sheet metal or metal casting without departing from the spirit-and scope ofmy A"in-t It will be furthercbserved'that though I have described the arcuatev wall and vention.

partition members as each ldisposed to subtend an angle of about thehopperwalls corresponding to 31 and 32 may be further divergent if thesealing wall be additionally extended.

It will thus be' observed that I havel provided an incinerator or'similar refuse dis-V posal system which is substantially simple andinexpensive, at thesame timeproviding a device which is fool-proofagainst undue loading to render the device inoperative and one which isfree from the obiections of disturbing the air currents in the flue ofthe Y incinerator by reason of the provision of a seal in all positionsof operation in respect to the loading opening. It will further beobserved that in the preferred form as shown, the hopper door is sodisposed as to automatically close upon release of the handle by theoperator after depositing any material in the hopper door.

Having thus described my invention and illustrated its use, what I claimas new and desire to secure by Letters Patent, is-

1. The combinationwith a flue wall having an opening therein, a framefitting into the opening comprising a frontal section formed with aplaster bead and inwardly directed flanges, a portion of which isarcuately formed, a rear section including an inwardly directed flangecomprising an angular extension at thev lower side and an arcuatelyformed wall at the top side, the anges of said sections being capable ofbeing fastened to form a smooth continuous1 arcuate wall and cooperatingto provide means for confining the masonry of the wall,

a hopper pivot concentric with the arcuate wall and a hopper embodyingdiverging sides proportioned as radii of an arc and moving upon thepivot with one of the sides at all times in Contact with the arcuatelyformed walls. u

2. The combination with a flue wall having an opening therein, a framefitting into the opening comprising a frontal section formed with aplaster bead and inwardly directed flanges, a vportion of which isarcuately formed, a rear section including an inwardly directed flangecomprising an angular eX- tension at the lower side. and an arcuatelyformed wall at the top side, the anges of said sections being capable ofbeing fastened to form a smooth, continuous, arcuate wall andcooperating to provide means for con- Y fining the masonry of the wall,a hopper pivot concentric with the arcuate wall and a hopper embodyingdiverging sides proportioned as radii of an arc and moving upon thepivotwith one of the sides at all times in contact with the arcuatelyformed walls, an outwardly turned lip on said frontal section for saidhopper pivot, angularlydisposed in subst-antial alignment with saidangular extension whereby a lateral and continuous extension is formedfor the hopper in its dumping position.

In witness whereof, I have hereunto signed my name this 11th day ofApril, 1927.
